Description
Claims (4)
- 複数のターボチャージャを備えた多気筒内燃機関にして、各ターボチャージャにて加圧された吸気は互いに異なる気筒群に供給されるようになっており、前記複数のターボチャージャにはモータアシスト式ターボチャージャとモータアシストされないターボチャージャとがあることを特徴とする多気筒内燃機関。
- 前記複数のターボチャージャのうちの第一のターボチャージャは第一の群の気筒のみからの排気により駆動されて該第一の群の気筒に対し過給を行い、第二のターボチャージャは第二の群の気筒のみからの排気により駆動されて該第二の群の気筒に対し過給を行うようになっていることを特徴とする請求項1に記載の多気筒内燃機関。
- 前記第一のターボチャージャがモータアシスト式ターボチャージャであり、前記第二のターボチャージャがモータアシストされないターボチャージャであるとき、前記第一のターボチャージャにより加圧された吸気の一部を前記第二のターボチャージャにより加圧された吸気に混入させる通路が設けられていることを特徴とする請求項2に記載の多気筒内燃機関。
- 前記複数のターボチャージャのうちの第一のターボチャージャはモータアシスト式ターボチャージャであって第一の群の気筒のみからの排気により駆動されて第二の群の気筒に対し過給を行い、第二のターボチャージャはモータアシストされないターボチャージャであって前記第二の群の気筒のみからの排気により駆動されて前記第一の群の気筒に対し過給を行うようになっていることを特徴とする請求項1に記載の多気筒内燃機関。
